Application filed June 14,

'lhis invention relates to a torce feed lubricator which is more particularly designed for pumping non-fluid oils and greascs to different bearings of machines which require lubrication.

rllhe object ot the invention is to provide a 'unitary device operated from a single sourc oi power which may be readily adpisted to independently regulate the volume ot heavy lubricant pumped to different discharge openings, whereby each bearing ot a machine may be supplied with the enact necessary amount et lubricant.

The embodiment oit' the invent-ion illustrated has a rotor contained in a cylinder within a casing. rhe rotor has a plurality ot' plungers that are each individually forced 'jorward 'by its own cam that is adjustably mounted in the casing. rlhe lubricant is 'fed under pressure into a commonchainber in the casing and passes therefrom through suitably arranged ports in the cylinder wall to spaces in trent oithe plungers and thev rotor is rotated the cams push the plungers forward and cause them to torce the lubricant that is in iront of them` through the several discharge ports that connect the cylinder with passages which lead through the casing. t I

ln the accompanying drawings lTig. 1 shows a i'front elevation, with parts broken away to expose the interior7 ot a lubricating pump that embodies the invention. Fig. is a view oi one end of the device. lFig. 3 is a t view of the other end. Fig. l is a transverse section on the plane indicated by the dotted line 4,4 on llig. 1.

rllhe casing 1 has along one side a chamber 2 into which the heavy lubricant is lorced through either the intake port 3 or the intake port 1, whichever ismost convenient, by any common means and at any desired pressure, ordinarily the heavier the lubricant the greater the pressure; 'lhese intake openings are threaded ttor the connection of pipes from the lubricant supply, and the opening not used is plugged. yllhc casing also contains a chamber 5 along the other side in which oil tor lubricating the parts ot the device itself' may be placed. 1n the center ot the chamber and extending its entire length is the cylinder (i. rlhe top ot the casing is closed by a removable cover 7, and one end oi the cylinthe cylinder is closed by a cap 9 which cylinder is closed by a cap 8 and the other end of ieee. serial No. H5391.

der covers are removably secured to the casing.

ln the cylinder is the rotor 10. `On one end of the rotor a ratchet wheel 11 is keyed. Engaging this ratchetwhcel isa pawl 12 which is pivoted to a lever 13 that is tree to turn on the end of the rotor; A spring 14 tends to keep the pawl carried by the lever in engagement with the ratchet teeth. "lhe lever has a number ot holes 15 which `provide means for the connection of the lever to any rotating or reciprocating part which is employed tor oscillating the ylever and causing the pawl to transmit an angular step `by step movement through the ratchet wheel to the rotor. By adjusting whatever connection is used from the driving mechanism to the different points ot the lever the amount ot this angular movement or the number of revolutions per minute given to the rotor may be va 'ied as desired. il pawl 16 is pivoted on the cylinder cap 9, and is heldk in engrfigenient with the ratchet teeth by a spring 17 to prevent any backward movement of the rotor.

ln the rotor shown there are live diametrically drilled holes 18 which holes are shown as extending through the rotor at angles differing by 36. 'lhe rotor may be provided with any desired number oithese holes and they need not be drilled at diiierent degrees, but it is preferred that they shall be, sothat the strains ot Jorcing the lubricant out ot the cylinder will be equallyy distributed throughout the revolutions of the rotor.

ln each of these diametrically drilled holes in the rotor is a plunger 19 that Apreferably has a head 2O at one end. rlhese plungers are preferably the same length as the diameter oi' the rotor.

Mounted in the casing in the planes oi rotation ot' the plungers and adapted to be swung in peripheral slots in the cylinder walls are cam levers 21 adapted to be engaged by the plunger heads. rlhese cams, which are retained in place by the casing cover are curved and their inner wallsare'sluipedv to the same arcs as the sections ot the cylinder wall they displace. i

1n the side of the casing opposite euch of these cani levers is an adjustable stop screw 22 that is adapted to be secured in place by a lock nut 23. These screws are designed to engage the outer surface ot the earn levers and determine the amount of their outward lil() movement during the operation of the pump. A rod 2st is extended from end to end of the casing in the chamber .5 to prevent the cam levers from opening so far as to allow the plungers to slip out of place and catching and wrecking the device.

A port 25 is made through the cylinder wall in the plane of rotation of each of the plungers, to provide communication from the chamber 2 to each of the plunger holes, and a port 26 is also made through the cylinder wall to the communicating discharge passages 27, 28 in casing in the plane of rotation of each of the plungers. Two discharge passages with threaded outer ends are desirably supplied for each discharge port in order that the tubes leading to the bearings to be lubricated may be most conveniently connected with the pump. The passage that is not used is plugged.

When this powerful, rugged, easily adjusted pump is put to use the lever 13 is connected with the operating mechanism so as to impart the desired step by step angular 'movement and speed to the rotor 10, and

the lubricant is forced into the receiving chamber 2 under the necessary pressure, which of course depends upon the character of the lubricant. As the rotor turns and a plunger 19 comes opposite a port 25 the lubricant under pressure in the receiving chamber liows through that port and iresses back that plunger until it is stopped y its cam 21, the lubricant occupying the space left at the front end of the plunger.

As the rotor continues to revolve the cam pushes the plunger forward and causes it to force the lubricant in front of it out through the port 26 to the discharge passage that is open. The quantity of lubricant that is delivered may first be varied by regulating the speed and angular movement of the oscillations of the lever that turns the rotor, and then the amount of lubricant that is forced to any particular bearing is further determined by the position of the cam that engages the plunger which forces the lubricant to such bearing. The stop screws 22 may be independently set so that the cams will coincide with the wall of the cylinder, in which case no lubricant will be forced to any bearing, or the screws may be set so that the cams will force the plungers their full movement and a full quantity of lubricant pumped, or the amount of lubricant pumped may be varied for each bearing, there being a widely ditiierent setting for each cam which determines the plunger movement and thus controls the amount of lubricant received and forced to the several bearings.
